The mother of a man who died in a fall in Ibiza has said she believes foul play may have contributed to his death.

Carl Morgan Shepherd, 28, known as Daniel, died after he fell asleep on his balcony at the Ibiza Jet Apartments, Playa d'en Bossa, in the early hours of August 14 2017.

"I don't believe he was sleeping, that's not my son, he's too intelligent, way too intelligent," Ms Shepherd said following an inquest hearing at Southwark Coroner's Court on Tuesday.

She said an argument allegedly took place at the apartment that night and, asked if she suspected foul play, she said: "I do, honestly."

Ms Shepherd also called for more to be done to help families dealing with the death of a loved one abroad.

She said: "This is where we need help with a governing body because it seems more and more youths are dying on holiday."

Ms Shepherd and her son's father, Colin Bascom, asked the coroner to adjourn the inquest until more evidence could be gathered.

Mr Bascom told the coroner, Briony Ballard, that he believed an unknown woman was in the apartment and could have been the last person to see his son before he died.

He said: "When I spoke to two of his friends - they were all renting the apartment together - one of them said that they and another person were together in the bedroom, a female. What I was told was that she had left and he had fallen asleep."

The friend's statement to the coroner contradicted this and said "they" had fallen asleep, meaning the girl may have still been in the apartment, Mr Bascom said.

"The one person who potentially had been the last to see my son alive has not submitted a statement," he added.

The coroner agreed to adjourn the inquest to allow the family to find the woman and submit a statement from her.

Mr Bascom also told the inquest he was surprised by the low blood alcohol level Danny had, especially as he was in Ibiza to drink and party.

"He could have driven a car at that level," he said.

"Danny was a party animal, and having extended his trip, I would have expected it to be higher."

But the court heard embalming fluid in his body could have affected the readings found in the post mortem.

As the press were speaking to the family after the hearing, Mr Shepherd's sister, Angel Bascom, 22, said she had tracked down the woman through Instagram .

Ms Bascom said the woman confirmed she was in Ibiza at the time.

The family said they were yet to get closure following Mr Shepherd's death and felt "exploited" and "blackmailed" by the Spanish funeral parlour who refused to release his body until they paid £6,000 in fees.

Ms Shepherd said: "People are exploiting the situation and making money off of us. Funeral parlours, they are exploiting us in our grieving moment. They blackmail you by holding on to your child's body."

Mr Bascom added they had not been contacted by the management of the holiday apartments where Mr Shepherd died, as they were "more interested in getting the party going again".

"Countless people said within hours (of Mr Shepherd's death) the party was swinging again," he said.
